Original application filed May 24, 1919, Serial No. 675,420. Patent No. 1,403,075, issued January 10, 1922. Divided and this application filed March 8, 1921. Serial No. 450,654.

To aZZ whom it may concern:

Be it known that I, DANIEL T. GLAcKm, a citizen of the United States, residing in Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Manifold Sheets, of which the following is a specification.

This application, which is a division of my co-pending application, Serial No. 299,- 543, filed May 24, 1919, (now Patent No. 1,403,075, dated Jan. 10, 1922) relates to a multiform billing sheet adapted for use in round-platen type-writing machines, and designed to furnish a number of identical copies of each original bill.

Owing to the inconvenience of handling webs in typewriting machines, partly because of their slipping and creeping, it is advanta cons to be able to make out a number of hills upon a comparatively short integral sheet, thus avoiding these and other 'difliculties. It is however, troublesome to insert the separate carbon-sheets if a bill of the type described is made out on a fanfolded sheet, inasmuch as such a sheet requires that the carbon-sheets shall be inserted from opposite sides. I

According to the present invention, if a bill-head need not occupy a length exceeding 5 inches, it may be made out upon a sheet wrapped several times around the platen of the typewriter, there being wrapped therewith, so as to be interposed between the layers, a carbon-sheet for making the carbon copies. To enable this to be done rapidly and economically, the typewriter platen may co-operate with fingers extending far enough around its periphery to carry a work-sheet around the top of the platen as it rises from the (printing point, and then bend it backwar ly and down wardly to the usual rear feed-rolls, thereby reintroducin the work-sheet between the platen and t e feed-rolls.

Other features and advantages will hereinafter appear. 7

In the accompanying drawings,

Figure 1 is a perspective view of a billhead and its four carbon copies shown removed from the platen when written out and before the carbon-paper is removed therefrom.

.Figure 2 is a vertical section through the platen and its cowoperating fingers, the'billhead being shown in position for typing.

Figure 3 is a diagrammatic perspective view, showing'the bill-sheet wrapped once around the platen.

Figure 4 is a similar view, showing it wrapped twice around the platen.

Figure 5 is a similar view, showing it wrapped three times around the platen.

Figure 6 is a diagrammatic perspective view, showing the bill-head partly written out, and broken away to show how the writing is superposed.

A platen 1 is fixed upon an axle 2 adapted to be journaled in the end walls of the usual typewriter carriage (not shown), as in the Underwood standard typewriter. When it is desired to make out a bill of the class described, that is, to provide one original bill and several copies, a sheet 6 is employed. The sheet 6, as shown in Figure 1, is folded so that one bill-head copy 8, which is printed upon the back of sheet 6, is folded over upon a carbon-sheet 9 which lies at the back of the rest of the sheet 6 (that is, the sheet minus the billhead copy 8). lhe bill-head copy 8 has a length equal to the circumference of the platen. It will be seen that the sheet comprises an original bill-head 11 and copies 8, 12, 13 and 14. Where the copy 8 is folded over, there is formed a leading edge 10. The carbon-sheet 9 lodges between sfheets 8 and 11 which form a pocket there- The leading edge 10 is inserted around the platen 1 in the usual manner, and the sheet 6 is held against the platen while the latter is turned, thus winding the sheet around the platen until the edge 10 is reintroduced at the rear thereof (see Figure 3). Upon further rotation of the platen, the bill- head copies 12, 13 and 14 will be wound around the platen and superposed one on the other. It will be seen that, as a result of the folding back of the forward end of the sheet over the leading end of the carbon-sheet 9, the latter will be held in osition with reference to sheet 6 when said sheet is inserted in the machine. It will be seen also that until the Figure 3 position is reached the carbonsheet lies between copies 8 and 11; in the Figure 4 position the carbon-sheet lies also between copies 11 and 13; and in the Figure 5 position between copies 12 and 13,

the platen. nearly to or below the level of the platenetc. By enclosing the leading edge of the carbon-sheet between the copies it is keptout of contact with the platen or the feedrolls 19 and 20, such contact resulting in'wrinkling of the carbon-sheet as is well known to typists. In order that the co ies when wound upon the platen may have t ieir identical lines superposed, the successive copies of the sheet 6, forming the bill- head copies 12, 13 and 14, are slightly longer, the difference amounting to less than one-- sixteenth of an inch in many kinds of paper, but depending upon the kindof paper used. This successive increase in length is necessary if the writing upon the bill-heads is to fall at identical spaces thereon, because, when the first bill-head is wrapped around the platen, its outer surface is of a circumference slightly greater than that of the platen, and this increases with each superposed thickness of the bill-heads. Thus, the top line 16 of cop 1 12 will coincide with edge 10, top line 1 of copy 13 will coincide with line 16 of copy 12, top line 18 of copy 1-1 will coincide with line 17 of copy 13, etc.

To aid in winding the sheet around the platen and holding the sheet in contact therewith, paper-fingers 22 are provided adjacent the platen. These fingers may extend down to the printing line or even down below the usual wing-scale 21 substantially to the front feed-rolls 20, the fingers being supported from a transverse rod 23 which extends between the end walls of the carriage (not shown). Each finger is supported from the rod 23 by slidable brackets '26, which embrace the rod and are held against revolving thereon by a key 27 held in a spline 28 on the rod by means of a spring 29 of a common form which stretches between the two brackets 26. The brackets are connected by a plate 30, and one of them carries an extension 31 having an elbow 32 to which a finger 22 is secured, as by rivetmg.

In order to guide the leading edge 10 downwardly behind the platen to the bite of the rear feed-rolls 19, thereby insuring the reintroduction of said leading edge between the platen and the feed-rolls, there is provided a second set of fingers 33 forming extensions of each finger 22, which are curved so as to fit closely the periphery of The fingers 33 extend down axle 2. In order to provide the flexibility of the fingers 33 needed to permit the fingers 22 to be swung up around the rod 23, the fingers 33 are each mounted upon a pivot 34 on the elbow 32 and are held against the platen by a s ring 35 which is sufiiciently.

strong to con no the leading edge 10 to the )urface of the platen after the platen is urned rapidly, but which, nevertheless, can

increase of the circumference be swung easily enough to permit the fingers 22 to be swung up.

Variations may be resorted to within the ranged in succession from top to bottom 7 of the sheet, the length of each form being substantially the same as, the circumference of the platen on which they are to be wound, the length of the forms being progressively increased from top to bottom so as to enable the outer forms to re 'ster, with the inner forms when wound a out the platen, and

a turned-over portion at one end of the sheet forming a pocket at the back of the sheet adapted to house the leading edge of a carbon sheet.
